The purpose of this app is to help readers get authentic answers from real experts timely and conveniently, instead of wasting time to google around but have no confidence whether the answer is correct or not.
My previous experience leads me to develop this app. As a former physics professor, I myself sometimes have questions to ask when I read books and papers. Also, I don't have answers for all the questions students raised. In fact, many professors are busy with research, and have little time to go outside their specialty to answer questions. Hopefully, within one's specialty, it won't take them too much time to answer questions. At this very early stage of this app, I've invited a few of my friends on board to be experts (mostly PhDs in Physics).
More experts/authors are welcome. Let's build a genuine connection between author/expert and reader/learner. Contact letmeask.app.help@gmail.com
